' I This invention relates to devicesqf or hanging the pulley block of ahoisting cableto a in the raising and lowering of logs in car loadingoperations." 1 In apparatus'of thischaracter it is deemed necessary tohave} the hanger" adjustably mounted upon the guy line so that thepulley :block may be brought into a position suitable for loadingoperations; and, when thus regulated, provision'fmust'be made forsecuring the hanger 'to theguy-line. e

Certain known pulley block supporting devices designed for this class ofwork are 5 objectionable because of liability of beinginr as I with ther to securely fastened to the supporting ,cable;

others are objectionable because the fastening means therefor aredi'flicult to manipulate in engaging and disengaging the same with'respect to the supporting cable; and others, again,.are" objectionablebecause they subj ect a'supporting cableto stresses and strains seve'rlyinjurious to the cable;

The object of the present invention is to provide ahoisting-cablepulley-hanger Whlch will overcome the objections above referred to andothers; which will be convenient to shift from one position to anotherand be secured at a desired position to the support- 'ing cable', andwhich will be peculiarly efiicient in operatioir p A further objectis'to p-rovidea strong and durable construction of hanger-frame, inwhich the securing parts are readily acces- These, and more specificobjectsjtogether" t' '11 advantages of the mven lon W1 wheel areapertured to receive a transversely disposed bolt .18 to support a link19 which,

In the accompanying drawing,- Figure l is aviewin longitudinal vertical section of pulley-block supporting devicesembodying myinvention, illustrated in engaged relation with a cableshown in side elevation; F ig. 2 is an end elevation and Fig. 3 is'aview, partly in horizontal section of Fig. 'lywithxtho cableomittedp MFig. 4 is a pictorialside elevation to. illustrate' the application ofthe invention."

Referring fi'r stto Fig. 4, the numeral 5 designates a cabletwhich,asshown, is utilized,

as'a guy for a post 6 the lower'endof the guy being secured to an anchor such, forje xample, as. aft'ree stump :7. Thefpurpose of r theinventionis to provide means for attachlngto the'c'able 5 a meansf8, lerelnafteifjdesignated generally as the carrier, whereby the cableserves to support apulley block!) pro vided with a sheave '10' for ahoisting cable 11 employed in the/loading of logs.

The carrier 8,. preferably of cast meta ll, H comprises two laterallyspaced side plates 12 3 Which'are connected at the topbytwo-longitudinally spacedfblock elements 13 ;'and, intermediate theirdepths, 'each of the side plates 12 is provided at its inner side with aledge 14 extending the entire. length, preferably, of the'carrierQ I iBetween said block elements l3,'thef respective side plates '12 areprovided with a pin Iii-which is disposed transversely of the carrierand constitutes the axle for a peripherally grooved wheel 16.

- In its underside each of the blocks 13 is provided with .alongitudinal groove 17,

which is arranged to slope upwardlv from the inner to'tlie outer endthereof, so that the grooves of both blocks taken together will bedisposed in angular relationonewith the lothe'ri The positioningof theblock grooves, moreover, are'suchthat the anglethereof is below the'periphery of the 'grooveof the wheel 16.

The side plates of the carrier below said.

in turn, engages witha hook or link 20 (Fig.

4) provided on the pulley block 9 to support the same.

The grooves 17 of the respective block ele- 'ments 13 areprovided withseries of recesses '21 formed-.as to shape and re1ativeposirier ledges14 and has in its top a longitudinal channel 23 of a segmental circularshape in transverse section to accommodate the underside of therespective portion of the cable5.. ,v A,

Thitwed channels, unlike the grooves in the block e ements 13, aresmooth (not corrugated) to permit unobstructed endwise movement oflthewedges with respect to the cable in effecting the upward flexing of thecable to have the strands thereof engage within the respective recesses21 of the block element grooves. a i

The wedges are driven byhammer blows into positions to set the'cableinto engaged relation, as above explained, with the carrier and, toh'ol'd'the wedges in positions to retain the cable in such engagement, Ipro vide a scr w threaded coupling bolt .24 extending through aperturedlugs 25 of both wedges, the head 26 of the bolt engaging the ,lu of onewed e anda nut 27 screwedon the r tengagingt elug of the other wedge.

To afford movement of the carrierto a selected position along the cable5, the wedges 22 are withdrawn from the carrier.

The cable then straightens as represented by dotted lines 5 in Fig. 1with a consequent disengagement of thecable from the carrier andtransferring the weight thereof (togethenwith that of other partsassociated therewith) from the giriooves 17 to the rotary .wheel 16which trac ng on the cable, ren-' .ders easythe shifting of the carrier.

It is tobe noted that the carrier is secured to the cable'bybendingthecable to cause the cable strands to engage in recessesprovided therefor 1n the carrier structure.
